In late 2368, the USS Enterprise-D traveled to Starbase 210 after being contaminated by a silicon-based clay lifeform from the planetPhaedra.

Thankfully, a method was developed to revert the organisms to their original form, and the Enterprise spent the next two weeks at the starbase undergoing repairs. (TNGnovel: Grounded)
